2 Claims.

This invention relates to ventilators and more particularly to animproved window ventilator which can be adjusted to either draw freshair into a room or exhaust stale air therefrom.

The principal objects of thisinvention are to provide an improved Windowventilator which can be mounted in a window opening and which is soconstructed that it can be adjusted to fit into various sized windowopenings; to provide a window ventilator of the aforementioned type inwhich the fan and driving means therefor are supported by a panel-likemember, and are enclosed by a grill which isadapted to be swung awayfrom the panel member to permit access to fit in various sized windows,a pair of transversely opposed, like end panels [5 are telescopicallyreceived between the upper and lower flanges 9 of the central panel 1.The end panels [5 are adjustably connected to the central panel 1 bymeans of bolts l! which pass through elongated horizontal slots l9,adjacent the upper and lower edges of the end panels [5. Nuts 20 arecarried on the bolts I! for securing the endpanels I5 to the centralpanel 1.

Therefore when the ventilator is inserted within a window opening, theend panels l5 can be moved inwardly or outwardly with respect to thecentral panel 1 so as to properly close and fit into the fan and drivingmeans; to provide a window the window opening, between the window sideventilator of the aforementioned type in which frame members l3. Thewindow sash H can then the fan and motor means therefor are rotatably bemoved to abut the upper edge of the ventilator, supported by the panelmember so that the fan as shown in Fig. 1, while the lower edge thereofmay be selectively swung to either a position for rests upon the windowsill 14. The outer ends of drawing fresh air into a room or to aposition for the end panels l5 are bent outwardly 90 to proexhaustingstale air from the room; to provide vide vertical flanges 23. Theflanges 23 are proimproved means for so rotatably supporting a fanvided, adjacent the upper and lower ends thereof, and its motor meansand for retaining the same with open L-shaped slots which are adapted inan adjusted position; to provide an improved for use in attaching theend panels to screws 24 ventilator of the aforementioned type which is25 threaded into the vertical window frame members especially neat inappearance, rugged in conl3. The central panel 1 is provided with acenstruction, and relatively inexpensive to manutral circular openin 21defined by an annular facture. outwardly projecting flange 3 I, for areason which These and other objects of this invention will willhereinafter appear. become apparent from the following detailed de- Agrill, generally indicated at 33, is hingedly scription taken inconjunction with the accomconnected to the inner face of the centralpanel panying drawings in which: I, over the panel opening 21.

The central panel 1, adjacent the latch mem her, isprovided with an aperture 55, so that when the grill 33 is in its normalvertical position the latch nose 53 will engage the outer face of theypanel 1, above the aperture 55, and retain the grill in its closed.position. In order to release the latch to permit the upper edge of thegrill to be swung away from the panel 1, about the tabs 45, as shown indot and dash lines in Fig. 2, a button 51 is slidably mounted in theupper leg of the grill, and abuts the latch 5| disposed therebelow. Bypushing downwardly on the button 51 the latch nose 53 will be moved outof engagement with the outer face of the central panel I, and intoalignment with the aperture 55 so that the entire grill can then beswung inwardly about the tabs 45. The central panel I has four rubbergrommets or tabs 58 secured to its inner face so as to abut each of thegrill corner gussets 4| when the grill is closed. The grill, as can beseen in the drawings, is provided with a central escutcheon cup 59.

Supported on the inner face of the central panel 1, within the grill,when the latter is closed, and in axial alignment with the panel opening21, is an electric motor enclosed in a housing 60. A drive shaft 6|projects outwardly through one end of the housing 60 and is operativelyconnected to a plurality of radially spaced fan blades 63, in. aconventional manner, so that the fan blades will be driven when themotor is operating. A transversfily extending horizontal strap 67 isprovided for supporting the motor on the panel 1. The strap 61 is offsetinwardly in the center thereof to fit the contour of the motor housingE0. and is secured to the housing 50 by means of studs and nuts H. Theopposite ends of the strap 61 are bent outwardly at right angles so asto extend parallel to the drive shaft 6| and provide end por tions 13. Abolt 15 has its threaded end extende ing outwardly through each of thestrap end por-. tions 13. 'A pair of channel section supporting brackets11 are secured to the inner face of the panel 1, adjacent each endportion of the strap 61, and each of the bolts 75 is journaled inits adejacent bracket. Wing nuts 19 are carried on the ends of the studs 75 tosecure the latter to the brackets H. The motor 59 and the fan blades 63are thus rotatably supported on the panel I, and by loosening the wingnuts 19 it is possible to roe tate the fan 180 from one position toanother. That is the fan and motor can be rotated either to the positionshown in Fig, 2, wherein stale air willbe blown out of the room,- or tothe position shown in Fig. 6 wherein the fan will blow fresh air intothe room. After the fan is in one or the other of these positions thewing nuts can be tightened to hold it in that position.

A conventional button type fan switch 8| is mounted on the inner face ofthe panel 1 adjacent the grill side wall 35, and is connected in serieswith the motor 60 and a conventional outlet plug 83, by means ofelectrical conduits 87. The conduit 81, connected to the motor 60, issecured to the supporting strap 61, adjacent the motor, by means of aclip 89, so that it is possible to rotate the motor 180 without breakingor tangling the same. Of course the fan and motor must be rotated backand forth in order to prevent winding o'f'the conduit around the strap51.

It will thus be seen that the fan blades can be rotated so as to eitherblow air into the room or push air therefrom, and that in order tochange the position of the fan, the grill latch 5i is depressed and thegrill pivoted away from the panel 1. The wing nuts 19 are then loosenedand the fan rotated to the desired position before again tightening thewing nuts. The grill can thenbe swung into its closed position so thatthe latch 5| holds it in place. The ventilator is-thus especially neatin appearance-,- easy to operate,

4 rugged in construction, relatively inexpensive to manufacture and canbe easily inserted in any conventional window, and withdrawn therefromwhen not in use.
